Thereby, fixation of the terminal of a seat cover (skin) and fixation of a wire harness can be performed simultaneously. However, the above configuration increases the manufacturing cost because the edge trim in which the harness holding portion is formed has a complicated shape.

  On the other hand, as shown in FIG. 7, the vehicle seat that attaches the wire harness WH to the suspended portion 91 of the seat cover 90 via the holding member 92 and holds the wire harness WH in the suspension groove 94 of the seat pad 93. It has been known.

JP-A-8-244507

  However, the configuration shown in FIG. 7 may cause the wire harness WH accommodated in the suspension groove 94 of the seat pad 93 to jump out of the suspension groove 94.

  In view of the above situation, the problem to be solved by the present invention is a vehicle seat in which a wire harness is arranged in a groove formed in a seat pad, and prevents the wire harness from jumping out of the groove. It is in providing the vehicle seat which can do.

  In order to solve the above problems, a vehicle seat according to the present invention is a vehicle seat to which a seat cover is attached so as to cover at least a part of a seat pad. The seat cover is provided on a cover body and a back side of the cover body. The holding member has an attached holding member, and the holding member is formed with an engaging member holding portion holding the engaging member on the distal end side and a harness holding portion holding the wire harness on the proximal end side. And the engagement member is bundled in the engaged member provided in the seat pad and in the groove formed in the seat pad, so that the wire harness is accommodated in the groove in the state of being accommodated in the groove The gist is that the cover is attached to the seat pad at a predetermined position.

  The seat cover is attached to the seat pad at a predetermined position by binding the engaging member held on the front end side of the holding member and the engaged member provided on the seat pad. And a wire harness is hold | maintained at the base end side of this holding member. In other words, the holding member that holds the engaging member that is bound to the engaged member does not jump out of the groove due to the binding of the engaged member and the engaging member, and is thus held by the holding member. The wire harness does not jump out of the groove.

  In addition, it is only necessary to provide a separation portion that separates the two portions between the engagement member holding portion and the harness holding portion in the holding member.

  The engaging member located on the distal end side of the holding member is bound to the engaged member provided on the seat pad by the binding member. During the binding operation, the wire harness may be damaged by the binding member. According to the above configuration, the engagement member and the wire harness are held in the holding member via the separation portion (the engagement member). And the wire harness are separated from each other), the risk of the wire harness being damaged by the binding member can be reduced.

  Further, in the configuration in which the separation portion is provided, the harness holding portion is formed such that the cross section of the wire harness insertion port, which is an opening for inserting the wire harness, is larger than the portion for holding the wire harness. The engagement member holding portion is an opening for inserting the engagement member formed at an end portion on the same side as the wire harness insertion port from a portion holding the engagement member. It suffices if the cross section is formed so as to have a larger cross section.

  As in the above configuration, the wire harness insertion port for inserting the wire harness in the harness holding portion is formed larger than the portion for holding the wire harness, and the engagement member insertion port for inserting the engagement member in the engagement member holding portion is If it is formed larger than the part which holds an engaging member, the workability | operativity which inserts a wire harness and an engaging member can be improved, without reducing the function to hold | maintain a wire harness and an engaging member. The reason why such a large insertion opening can be formed at the end of the holding member on the same side is that a separation portion is formed between the harness holding portion and the engaging member holding portion. In other words, the above-described configuration is a technique in which the insertion port formed at the end portion on the same side is set to be large by skillfully utilizing the existence of the separation portion between the two holding portions.

  In addition, the harness holding portion is formed so that the cross section of the wire harness insertion port, which is an opening for inserting the wire harness formed at one end of the portion holding the wire harness, is larger, The engagement member holding portion has a larger cross section at an engagement member insertion port which is an opening for inserting the engagement member formed at the other end than the portion holding the engagement member. It may be formed.

  As in the above configuration, the wire harness insertion port for inserting the wire harness in the harness holding portion is formed larger than the portion for holding the wire harness, and the engagement member insertion port for inserting the engagement member in the engagement member holding portion is If it is formed larger than the part which holds an engaging member, the workability | operativity which inserts a wire harness and an engaging member can be improved, without reducing the function to hold | maintain a wire harness and an engaging member. In addition, since the harness insertion port and the engaging member insertion port are formed at opposite positions, it is not possible to increase the size of one insertion port to increase the size of the other insertion port. Therefore, the above-described configuration is particularly effective when the separation portion is not present between the two holding portions (when both holding portions are adjacent to each other).

  The vehicle seat according to the present invention has a configuration in which the wire harness is held by the holding member that holds the engaging member that is bound to the engaged member provided on the seat pad. Can be prevented from jumping out of the.

It is an external appearance perspective view of the holding member of a 1st modification. It is an external appearance perspective view of the holding member of a 2nd modification. It is a figure for demonstrating the wiring structure of the conventional wire harness.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The vehicle seat 1 according to the first embodiment includes a seat pad 20 and a seat cover 10 (skin) attached so as to cover at least a part of the seat pad 20. In addition, although the following description demonstrates the structure of the seat cushion 31 (sitting part) as an example, it is applicable also in the seat back 32 (backrest part). Further, since a known configuration can be applied to the seat frame, which is the skeleton of the seat, a detailed description is omitted.

  The seat cover 10 includes a cover body 12 and a holding member 11. The cover main body 12 is a main body portion of the seat cover 10 that covers the seat pad 20. For example, it is composed of a main cover 121 that covers the center of the seat pad 20 and a side cover 121 that covers the outside in the width direction of the seat pad, and the stitched portions of the main cover 121 and the side cover 122 are drawn into a suspension groove 21 described later. It is. Hereinafter, the portion of the cover body 12 that is pulled into the suspension groove 21 may be simply referred to as a pull-in portion 123.

  The holding member 11 is a member attached to the retracting portion 123 of the cover main body 12. The holding member 11 in the present embodiment is a bag-like member made of a cloth that is difficult to stretch, such as cotton cloth. Specifically, both ends in the width direction are sewn to the pull-in portion 123 in a state where a long cloth along the pull-in portion 123 of the cover body 12 is bent in the width direction so as to have a cross-sectional bag shape. The holding member 11 is provided with a cover-side wire holding portion 111 (corresponding to an engaging member holding portion in the present invention) and a harness holding portion 112. Each holding portion is a space having a predetermined size formed by dividing (dividing) the space inside the bag-like holding member 11. That is, each holding part is a long space in the direction along the drawing-in part 123. In the present embodiment, one space partitioned by sewing the central portion of the holding member 11 in the direction along the pull-in portion 123 (longitudinal direction of the holding member 11) becomes the cover-side wire holding portion 111, and the other space. Becomes the harness holding portion 112. As shown in the figure, a cover-side wire holding portion 111 is formed on the distal end side of the holding member 11 far from the portion sewn on the drawing portion 123, and the base of the holding member 11 close to the portion sewn on the drawing portion 123 is illustrated. A harness holding portion 112 is formed on the end side.

  The cover-side wire holding portion 111 holds a cover-side wire W1 (corresponding to the engaging member in the present invention). The cover-side wire W1 is a metal elongated bar-shaped member. The cover-side wire holding part 111 is desirably formed in a size that prevents the inserted cover-side wire W1 from moving. A plurality of through holes 114 are formed in the cover side wire holding portion 111 in the thickness direction of the holding member 11 (through the direction perpendicular to the longitudinal direction of the holding member 11).

  On the other hand, the harness holding part 112 holds the wire harness WH. The wire harness WH includes one or a plurality of various electric wires such as power lines and signal lines of electrical elements provided in the vehicle. The harness holding portion 112 is desirably formed in a size that prevents the inserted wire harness WH from moving greatly. Specifically, the size of the cross section of the harness holding portion 112 only needs to be slightly larger than the size of the cross section of the wire harness WH.

  The seat pad 20 is formed with a suspension groove 21 (corresponding to a groove in the present invention) into which the retracting portion 123 of the seat cover 10 is retracted. The position where the suspension groove 21 is formed is not particularly limited. A pad-side wire W <b> 2 (member to be engaged in the present invention) is embedded on the bottom surface side of the suspension groove 21 in the seat pad 20. The suspending groove 21 has a plurality of relatively deep portions (not shown), and the pad-side wire W2 is exposed at the portion. The position of the portion where the pad side wire W2 is exposed is formed in accordance with the position of the portion where the through hole 114 is formed in the holding member 11. That is, in the longitudinal direction of the holding member 11, the exposed position of the pad-side wire W <b> 2 and the position of the through hole 114 are set to substantially coincide.

  As shown in FIG. 2B, the pad-side wire W <b> 2 (exposed portion thereof) and the cover-side wire W <b> 1 are bound by the binding member H that passes through the through hole 114, so that the retracting portion 123 of the seat cover 10 is suspended. The seat cover 10 is attached to the seat pad 20. That is, the holding member 11 is pulled into the hanging groove 21. Since the wire harness WH is held in the harness holding portion 112 of the holding member 11, the wire harness WH is housed in the suspension groove 21.

  In the present embodiment, the cover-side wire W <b> 1 is held by the holding member 11. Therefore, as long as the cover-side wire W1 is bound to the pad-side wire W2, the holding member 11 does not jump out of the suspension groove 21. Thus, the fact that the holding member 11 does not jump out of the hanging groove 21 means that the wire harness WH held by the holding member 11 does not jump out of the hanging groove 21. That is, according to this embodiment, the wire harness WH routed in the suspension groove 21 of the seat pad 20 can be prevented from jumping out of the suspension groove 21.

  Next, the vehicle seat 2 according to the second embodiment will be described focusing on differences from the vehicle seat 1 according to the first embodiment, specifically, the structure of the holding member 11 '. The holding member 11 ′ of the vehicle seat 2 according to the present embodiment is the first implementation in that a separating portion 113 is provided between the cover-side wire holding portion 111 and the harness holding portion 112 so as to separate both portions. It differs from the vehicle seat 1 according to the embodiment.

  That is, the holding member 11 ′ of the present embodiment includes a cover-side wire holding portion 111 that is a space formed on the distal end side, a harness holding portion 112 formed on the proximal end side, and a separation formed between them. The unit 113 is divided into three parts. Specifically, the holding member 11 ′ is sewn in the direction along the lead-in portion 123 (longitudinal direction of the holding member 11 ′) so as to be partitioned into these three regions (the cover-side wire holding portion 111 and the separation portion 113, And the harness holding part 112 and the separation part 113 are sewn together).

  The size of the separation portion 113 is not limited to a specific size. Since such a separation portion 113 is formed, the position where the cover-side wire W1 is held and the position where the wire harness WH is held in the holding member 11 ′ are separated from each other by providing the separation portion 113. When the side wire W1 and the pad side wire W2 are bound by the binding member H, the wire harness WH can be prevented from being damaged by the binding member H. When such a separation part 113 is formed, the through hole 114 through which the binding member H is inserted is as close to the cover side wire holding part 111 as possible as shown in FIG. The cover side wire holding part 111 may be formed on the cover side wire holding part 111 in the same manner as in the first embodiment.

  Here, in the present embodiment, the stitched portion that divides the harness holding portion 112 and the separation portion 113 may be only a location corresponding to the binding position. That is, since the separation part 113 prevents the wire harness WH from being damaged by the binding member H, it is only necessary that the cover-side wire W1 and the wire harness WH are positioned apart from each other at the binding position. Therefore, as shown in FIG. 4, in the direction orthogonal to the longitudinal direction of the holding member 11 ″, the harness holding portion 112 and the separation portion 113 are partitioned so as to overlap the through hole 114 through which the binding member H is inserted. The part S may be formed locally. In this way, since the wire harness WH does not move to the cover-side wire W1 side at least at the location where the stitched portion S is formed, the wire harness WH is damaged by the binding member H. Can be prevented. The “partition” in the present embodiment includes a configuration in which the harness holding part 112 and the separation part 113 are locally partitioned in this way.

  As a modification (improved example) of the embodiment of the present invention described above, the following configuration is conceivable.

  As a modified example (first modified example) of the second embodiment, a configuration as shown in FIG. 5 can be considered. In such a configuration, in the harness holding portion 112, the harness insertion port 112a has a larger cross section than the portion 112b that holds the wire harness WH. The portion 112b for holding the wire harness WH is a portion for holding the inserted wire harness WH so as not to move greatly. The cross section of the part 112b only needs to be formed slightly larger than the cross section of the wire harness WH. On the other hand, the harness insertion port 112a is an opening for inserting the wire harness WH. As shown in the drawing, the harness insertion port 112a having a larger cross section than the portion 112b for holding the wire harness WH is formed at both ends in the longitudinal direction of the holding member 11′i, thereby having a function of holding the wire harness WH. The workability of inserting the wire harness WH into the harness holding part 112 can be improved without lowering.

  Similarly, in the cover-side wire holding part 111, the cover-side wire insertion port 111a has a larger cross section than the portion 111b that holds the cover-side wire W1. The portion 111b for holding the cover-side wire W1 is a portion for holding the inserted cover-side wire W1 so as not to move greatly. The cross section of the part 111b only needs to be formed slightly larger than the cross section of the cover-side wire W1. On the other hand, the cover side wire insertion port 111a is an opening for inserting the cover side wire W1. As shown in the drawing, the cover side wire W1 is formed by forming the cover side wire insertion port 111a having a larger cross section than the portion 111b for holding the cover side wire W1 at both ends in the longitudinal direction of the holding member 11′i. The workability of inserting the cover-side wire W1 into the cover-side wire holding part 111 can be improved without reducing the function of holding.

  Thus, in the first modified example, the harness insertion port 112a formed at both ends of the harness holding portion 112 and the cover side wire insertion port 111a formed at both ends of the cover side wire holding portion 111 are formed large. This improves the workability of inserting the wire harness WH and the cover-side wire W1. Since the separation part 113 is formed between the harness holding part 112 and the cover side wire holding part 111, the insertion ports of both holding parts located on the same side (one end part in the longitudinal direction) should be enlarged. Can do. In other words, if the separation portion 113 is not formed and both holding portions are formed side by side, when the insertion port of one holding portion is enlarged, the other insertion port located on the same side must be reduced. However, since the separation part 113 is formed between both holding parts in this modification, the insertion port of both holding parts located on the same side can be enlarged. That is, in this modified example, both holding portions located on the same side are skillfully utilized by forming the separation portion 113 that separates both holding portions so that the wire harness WH is not damaged by the binding member H. This is a larger insertion slot. In other words, the presence of the separation portion 113 expresses two effects of “preventing damage to the wire harness WH” and “enlarging the insertion port located on the same side”.

  In this modification, the cover side wire insertion port 111a and the harness insertion port 112a may be formed at both ends of the holding member 11 as shown in FIG. It is good also as a structure formed only in the side. If it is the structure formed in the both ends, since the wire harness WH and the cover side wire W1 can be inserted from two directions, the workability of the assembly is improved.

  On the other hand, as a modified example (second modified example) of the first embodiment, a configuration as shown in FIG. 6 can be considered. In this configuration, in the harness holding part 112 and the cover side wire holding part 111, the harness insertion port 112a and the cover side wire insertion port 111a are located more than the part 112b holding the wire harness WH and the part 111b holding the cover side wire W1. Has a large cross section. In addition, the suitable magnitude | size of the site | part 112b holding the wire harness WH and the site | part 111b holding the cover side wire W1 is as having demonstrated in the 1st modification. The harness insertion port 112a is formed at one end in the longitudinal direction of the holding member 11i, and the cover side wire insertion port 111a is formed at the other end in the longitudinal direction of the holding member 11i. That is, both insertion ports are located on the opposite side.

  Thus, unlike the first modified example, this modified example does not have a configuration in which the separation part 113 is formed between the harness holding part 112 and the cover-side wire holding part 111, and thus holds the wire harness WH. The insertion port formed larger than the part 112b and the part 111b holding the cover-side wire W1 cannot be formed on the same side. Based on this, the large formed insertion port is positioned on the opposite side. Thereby, it is possible to form the large insertion opening for facilitating the insertion of the member to be held at the end on at least one side of the both holding portions.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment at all, A various change is possible in the range which does not deviate from the summary of this invention.
